dell laptop battery

After manual sorting, are sorted out in the trash, such as fever thermometers and large batteries, the battery mixtures usually are automatically sorted by size, then separated by the electro-chemical systems. For sizing is screened, the detection of the Dell Studio 1537 battery system and the subsequent separation, through the deflection of a magnetic field (Titalyse-TriMag process, eg in the GMA in Wiefels, Lower Saxony) take place. Another option is the use of X-ray method: The batteries are passed through an X-ray sensor. The battery system is recognized by the gray scale of the X-ray image.

Older zinc carbon and alkaline manganese batteries often contain large amounts of mercury to be used directly as raw material in the zinc smelting can. Therefore, the newer, low-mercury batteries for the visual detection of a UV-codes are sorted out. The purity of the separated fractions depends to a large degree on the cleanliness of the supplied battery mixtures, for example, can be due to moisture greatly influences corroded battery mixtures only with worse results than separate clean, not corroded quantities.

The possible recycling routes for the sorted fractions battery focus on the recovery of metals such as nickel, lead, mercury and silver, iron, nickel and copper. Either the Dell Vostro 1510 battery can be directly utilized in Sekund?rverhüttung, as with car batteries and small lead-acid batteries is already applied, or there must be preceded by processing steps to separate interfering substances in advance.

To separate the metals, electrolytic processes have not proven successful. More favorable thermal processing steps (eg W?lzrohrofen), the fractions obtained can be attached to the Sekund?rverhüttungsproze?. The separation of the resulting battery is in the following groups, where possible recycling methods are compared:

To use the battery in fractions Sekund?rverhüttungsprozessen, you must be a possible selective separation. Interfering metals (Cd, Hg and / or Cu) may be present only in vanishingly small quantities. The sorted batteries must therefore go through some preliminary processes. The more upstream processing steps are required, the lower the recovery of the associated environmental benefits, since the number of processing steps including the necessary energy use is increased.

Zinc carbon and alkaline manganese batteries, which represent the majority of all used batteries can be used in the nonferrous metals industry and the iron and steel industry (eg in W?lzrohrofen or electric arc method). A problem still exists in the mercury content of older batteries. The mercury content in these at up to 100 ppm (ie, in a tonne of batteries can be sorted out include up to 100 grams of mercury). For a smooth recovery in the metals industry, the mercury content of the Dell XPS M1530 battery set are ppm less than 5. This low mercury content must be maintained with the entry into force of the amended regulation battery 2,001th In some years, therefore, hardly any mercury in the collected batteries to be, the recycling of zinc carbon and alkaline manganese batteries will then not only ecologically but also economically more reasonable. Until then, is expected to get a partial fraction of the alkaline manganese and zinc carbon batteries are disposed of in special landfills.

NiMH batteries can easily be recycled together with steel scrap. A pre-treatment is only modestly (opening the cell) is necessary. By the content of nickel and cobalt recycling is economical.

NiCd cells are also recycled. This must be first separated in separate processes, the cadmium that can be marketed only with difficulty.

Auto-/Starterbatterien

For the return of car batteries, the battery provides regulation no common collection system of the manufacturers. was withdrawn because usually when changing car batteries in automotive repair shops and gas stations the old battery is already, for these batteries (about 14 million units, car batteries with approximately be. 190,000 tonnes of lead a year on the market.) high return and recycling (about 95%.) already achieved. To ensure that all batteries, the buyer must pay when buying a new battery for a deposit of $ 15 if he returns at the same time an old battery. The deposit will be returned on subsequent return of an old Dell inspiron 1525 battery.

One of the producers commissioned disposal facility or a scrap dealer will pick up at the request of the dealer of used starter batteries. The same applies to the public collection (recycling centers or contaminant Mobile). The collection points are still required to charge car batteries, used to receive. To pay the mortgage money, they are not obliged by the Regulation. In several secondary lead smelters, lead is recovered from the batteries and usually for new batteries used.

Conclusion

The battery regulation of product responsibility of manufacturers provides comprehensive application. To relieve the household of pollutants, the return obligations of the consumer just as important as increased efforts to find a good screening technique and the design and development of environmentally meaningful recovery. The Dell Inspiron 6400 battery
with the amendment of Ordinance 2001 which came into effect limiting the mercury content of zinc carbon and alkaline manganese cells is another important step towards an environmentally and economically sound recycling. Problematic and unsatisfactory at present is particularly the 33% is still very low return rate for portable batteries and the associated uncontrolled entry of pollutants into the environment. In the future, increased efforts are essential to increase the response rate.
